sup fellow LTS dude, alright look- get a *good* air-gun, 175PSI, set TDC and *zapp* that "blocker" off. Also get/rent whatever a "twim cam locking plate"

BTW: I just finished installing a P/P head, when you are ready to get the belt on start on the crank with the tension on the intake- trust it will make installation soooooooo much easier. dont just try and slip it over all at once.

uhm- - i'm asuming you've done this before :wink:

Easiest way is to put a breaker bar/ratchet on the bolt, resting the handle on the axle or a-arm. Then crank the engine over (don't let it start though) and it will break the bolt loose for you.

I have an air gun but only 150psi, haven't tried it yet...

breaker bar and ratchet ? doesn't it spin clock wise ? (the crank that is)


So far I stuck it in gear.. and got some one to step on the breaks.. but.. I Was still able to .. turn the wheels 8O ...

Yes the crank spins clockwise, so when you crank it over it loosens the bolt. As you hold the bolt in place and spin the crank clockwise, it is spinning the bolt itself counter-clockwise (since it is held in place by the ratchet/breaker bar).

Yes it will. I have done it on my car 3 times now and the bolt was torqued to 115 ft lbs or so. Just don't try to hold the wrench (or have anynoe else hold it for that matter) or anything because you'll lose a finger or hand if the wrench slips 8O.

hehe on mym sisters 4.3 v6 vortec powered s10 it has that huge nut/bolt type deal on the fan/clutch-pully connection. My brother in law finally found the worlds largest crescent wrench to go around the thing and we still couldn't get it off. It turned all the pullys with it! so... finally remember I had a rubber mallet in the truck. a couple real hard hits finally got it to crack free enough that we could turn it without everything else turning with it.

See I told you it would work :D.

When you say wedge I don't really know what you mean. The only thing I can think of is the key that aligns the crankshaft and pulley? If it's that, I think you should be able to either wiggle it out with pliers or wiggle the whole pulley until it loosens up and comes off. I personally have a 1.9 and I haven't done it on a 1.8 yet.

Well from what I can tell, once you have the crankshaft pulley off all you need to do is loosen the timing belt tensioner and the belt should come off. I don't think you need to take the whole crankshaft sprocket off.

Ah yes that's the sprocket keyway key. You should be able to get the pulley off without removing the key. You can make a puller out of 3 of the bolts and a piece of metal if you really have to. You will have to use the large center bolt and two of the outer ones. Make a piece of stiff metal that can go across and has 2 holes in it, one for each side bolt to go through. Now put the large center bolt into the crank about half way in. Take the metal piece and align it so you can put the two side bolts through. Now alternate tightening the side bolts and it will slowly pull off the pulley. Make sure to evenly tighten them so they don't get angled and strip out. If you have ever used a cheap steering wheel puller you will understand exactly what I am talking about. Hopefully that may help you :wink:

Here's the procedure as described in the shop manual for a '93 LX.
Sorry it won't copy the graphics.

The following illustration shows an exploded view of the timing belt and its related components.



1. Remove the timing belt upper cover and gasket.



2. Loosen the water pump pulley bolts.

3. Remove the generator and water pump drive belt. Refer to «Section 03-05A».

4. Remove the water pump pulley bolts and remove the pulley.

5. Raise the vehicle.

6. Remove the RH wheel.

7. Remove the RH upper splash shield.

8. Remove the RH lower splash shield.

9. Remove the A/C (if equipped) and power steering accessory drive belt. Refer to «Section 03-05A».

10. Remove the crankshaft pulley, crankshaft pulley guide plate and timing belt outer and inner guide plates.





11. Remove the timing belt middle and lower covers along with the gaskets.

12. Rotate the crankshaft and align the timing marks located on the camshaft pulleys and the seal plate.



13. If the timing belt is to be reused, mark an arrow on the belt to indicate its rotational direction for installation reference.

14. Loosen the timing belt tensioner lock bolt and remove the timing belt.


Installation

1. Temporarily secure the timing belt tensioner in the far left position with the spring fully extended, then tighten the timing belt tensioner lock bolt.

2. Verify that the timing marks on the timing belt pulley and the engine block are aligned.



3. Verify that the timing marks on the camshaft pulleys and the seal plate are aligned.



4. Install the timing belt.

5. Loosen the tensioner lock bolt. Using a suitable prying tool, position the timing belt tensioner so that the timing belt is taut, then tighten the tensioner lock bolt.

6. Turn the crankshaft two turns clockwise and align the timing belt pulley mark with the mark on the engine block.

NOTE:
If the timing marks are not aligned, remove the belt and repeat the procedure.

7. Verify that the camshaft pulley marks are aligned with the seal plate marks.

8. Turn the crankshaft 1-and-5/6 turns clockwise and align the timing belt pulley mark with the tension set mark (at approximately the 10 o'clock position).



9. Apply tension to the timing belt tensioner and install the tensioner lock bolt. Tighten the timing belt tensioner lock bolt to 37-52 N-m (27-38 lb-ft).

10. Turn the crankshaft 2 and 1/6 turns clockwise and verify that the timing marks are aligned.

11. Measure the timing belt deflection by applying 98 N (22 lb) of pressure on the belt between the camshaft pulleys as shown.



The timing belt deflection should be 9-11.5mm (0.35-0.45 inch). If necessary, adjust the timing belt deflection as explained in this section.

NOTE:
If the timing marks are not aligned, repeat the procedure beginning at Step 4.

12. Turn the crankshaft 2 turns clockwise and verify that the timing marks are aligned.

13. Install the timing belt middle and lower covers along with the gaskets.

14. Install the timing belt inner and outer guide plates, the crankshaft pulley and the crankshaft pulley guide plate. Tighten the crankshaft pulley bolts to 12-17 N-m (109-152 lb-in).

15. Install the A/C (if equipped) and power steering accessory drive belt. Refer to «Section 03-05A».

16. Install the RH upper splash shield. Tighten the splash shield bolts to 7.8-11 N-m (69-95 lb-in).

17. Install the RH lower splash shield. Tighten the splash shield bolts to 7.8-11 N-m (69-95 lb-in).

18. Install the water pump pulley. Tighten the water pump pulley bolts to 7.8-11 N-m (69-95 lb-in).

19. Install the generator and water pump drive belt. Refer to «Section 03-05A».

20. Install the RH wheel.

21. Lower the vehicle.

22. Install the timing belt upper cover and gasket. Tighten the timing belt upper cover bolts to 7.8-11 N-m (69-95 lb-in).
